"Unable to open the Server service performance object."
When looking into this there seem to be two different things that can cause this problem.
Your running sharepoint in which case the recommendation is to update sharepoint if possible or try and rebuild performance counters.
There is some application that need to collect network performance data. To collect this data the account running this application need to be lcoal administrator on the server or it will not get access and this error will show up in event log.
